IMPROVED PARLORSTOVE- Specification forming part of Letters Patent No. 44.430. dated September 27, 1864.

To all whom it may concern:

Be it known that I, SUMNER HYDE, of Williamsburg, in the county of Hampshire and State of Massachusetts, have invented a new and Improved Stove; and I do hereby' declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part ot' this specification, in whichl Figure l is a vertical central section of my invention, x tv, Fig. 2, indicating the line of section; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. 1.,

Similar letters of reference indicate corresponding parts in the two gures.

This invention relates to a new and improved stove for burning fine fuel, such as shavings, sawdust, iine coal, or coal dust.

The invention consistsl in the employment or use of an outer and inner case, between which there are vertical partitions, the inner case being perforated, and all arranged as hereinafter set forth, whereby air is admitted into the body of the fuel to insure its perfect combustion, and at the same time heat allowed to be radiated from the outer cylinder.

rlhe invention further consists in using in connection with the two cases aforesaid a registergrate arranged in such a manner as to not only control the amount of air required to feed the fire from below, but also to serve as a raking device to free the fuel from ashes.

A represents the lower part or base of the stove constructed of cast iron, and B isa sheetmetal cylinder, which forms the body of the stove. C is an inner cylinder, composed of vertical sections a, fitted together and se cured in position by means of lips b, or other means. These sections are of cast metal, and they are provided at their outer sides with vertical radial plates c, which form partitions between the two cylinders, and divide the lspace into two series of compartments, d c,

which extend the whole height of the stove, or nearly so, and are closed at their upper ends.

The sections a of the inner cylinder, G, are provided, respectively, with perforations f f which communicate with the compartments d e. The compartments d -are closed both at their upper and lower ends, but the compartments c communicate with the ash-pit D by means of perforations g in the base A.

From the above description it will be seen that the body of the fuel will be supplied with air which passes through the ashpit D,through the perforations g, and thence up into the compartments e, and through the perforations j" into the body of the fuel, as indicated by the black arrows, while the compartments d serve as heat-radiating chambers, and admit of a direct communication between the body of the stove and the outer case, B, as indicated by the red arrows in Fig. 1. The heat-radiating chambers d. are much larger than the chambers or compartments e, as shown clearly in Fig. 2. l

The fuel is also supplied with air through the grate at the top of the ash-pit D, which is made in it, and provided with a perforated plate, 1'., at its center, the plate E having an annular plate, F, upon it, which is also provided with radial slots j, and has its center fitted around guide pins k on the plate E.

rlhe two plates E F serve as a register, by which, on adjusting the annular plate F, the amount of air admitted to the bottom of the fuel may be regulated as desired, and the tire also raked or deprived of ashes.

The products of combustion pass directly up into the smoke-pipe G, as will be understood by referring to Fig. l.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. Theinnercylin of vertical sections, a, provided with radial plates c at their outer sides to form partitions and divide the space between the two cases into compartments d e, which communicate with the interior ofthe stove by perfor-ations f j", the compartments e communicating with the ash-pit D, and all arranged substantially as and for the purpose specified.

2. The register at the bottom of the stove composed of the two plates E F, provided with perforations, substantially as described, when used in combination with the two-cases B C, with the vertical partition-plate c between them, substantially as and for the purpose set forth.
